China is the largest producer of natural zeolites, with nearly 69% of global production in 2016, followed by South Korea, Turkey, and Japan. Other than the large volumes in these countries, world production is highly decentralized. The largest end use for natural zeolites is as a cement additive, to produce a slower-hardening and stronger product.
Superior water treatment with the naturally absorbent and non-toxic mineral zeolite. Water treatment refers to the removal of impurities (microorganisms, suspended solids or dissolved substances) from drinking water, industrial wastewater, hot tubs and the like.
In this study, zeolite was employed for the separation and recovery of P from synthetic wastewater and its use as phosphorus (P) source for the cultivation of the green microalga Chlorella vulgaris and the cyanobacterium Arthrospira (Spirulina) platensis.At P-loaded zeolite concentration of 0.15–1 g/L, in which P was limited, the two species displayed quite different behavior regarding their ...

The ion-exchange process is the most attractive, simple and cost effective method to remove the toxic elements in waste water. Natural zeolite mineralcontains exchangeable cations, such as Na+, K+, Ca2+, and Mg2+, in its structural framework. Ammonium and heavy metal ions in wastewater is replaced by these cations during ion exchange.
1.3.2 Use of Synthetic Zeolite for Wastewater Treatment The use of synthetic zeolite for the environmental protection is stimulated by its good physico-chemical properties e.g. selective sorption,its non-toxic nature and availability. A great deal of research on zeolite has focused on a wide range of 21 applications including waste water ...
Apr 01, 2020· Zeolite Products (2014) is a company that produces zeolites for water and wastewater treatment with a commercial name (Zeo WT). Zeo WT is an ecological product, made exclusively from natural zeolites for use in the process of biological wastewater treatments.

We specialize in the development and production of special filter materials. Activated filter glass, antibacterial zeolite, activated zeolite, zeolite filter cleaner, zeolite activator, zeolite activation solution for treatment of drinking, waste, process and pool water and other applications.
The application of ion exchange process for ammonium (NH4+-N) removal from wastewater is limited due to the lack of suppliers of engineered zeolites which present high ammonium exchange capacity (AEC) and mechanical strength. This study focuses on the preparation and evaluation of synthetic zeolites (Zeolite1-6) by measuring AEC and resistance to attrition and compression, against natural ...
Zeolite (as Zelflocc) provides a process for the enhancement of wastewater purification systems which utilises the unusual properties of the natural mineral zeolite to improve the performance and/or capacity of existing treatment systems, or to reduce capital expenditure on new treatment systems.
Currently, there are challenges with proper disposal of cassava processing wastewater, and a need for sustainable energy in the cassava industry. This study investigated the impact of co-digestion of cassava wastewater (CW) with livestock manure (poultry litter (PL) and dairy manure (DM)), and porous adsorbents (biochar (B-Char) and zeolite (ZEO)) on energy production and treatment efficiency.
